What's a VNC Server? A server is a piece of computer hardware or software that provides capabilities for other programs called “clients. VNC stands for Virtual Network Computing. It is, in essence, a remote display system which allows you to view a computing `desktop'. 1. Determine port number on which VNC server listens. It can be calculated like this: + {display number}. · 2. Now open the VNC Viewer application and. WINSCP IPHONE 6

To set x11vnc to continually listen for connections, include the -forever option. To put x11vnc in view-only mode, include the -viewonly option. To set x11vnc to only allow local connections, include the -localhost option. Xauth -display :0 options to be specified on the command-line. The argument value for the -auth option may be found previously with x11vnc -findauth.

Xauth -display :0 If you find a blank screen, check the x11vnc FAQ entry on headless servers. Because it's highly integrated with KDE, running it in other environments is difficult. To set krfb to request access each time, tick Confirm uninvited connections before accepting To set a password, type a hard-to-guess password into the Password input box. To put krfb in view-only mode, untick Allow uninvited connections to control the desktop.

There's no built-in way to only allow local connections, although see below for a solution. Once mode Krfb doesn't have a built-in way to accept the next connection then stop listening for connection attempts. However, the following Python script will listen for a single connection then exit krfb:! Make sure that the initial ' ' character is the very first character in the file, save the file as krfb. Although this simple program won't open a window of any kind, it will quietly wait for the next VNC client to connect to your computer, then pass the connection through to krfb.

This script will only listen for local connections. To allow connections from anywhere, change Invitations Krfb lets you create "invitations", or individual passwords that are deactivated after an hour or after one use. These are a handy way of giving people one-time access to a computer, but only provide limited security. For example, if you send someone an invitation by e-mail or instant messaging, an attacker could read your invitation message as it went over the Internet and use it to log in.

Invitations can be useful when you want to let other people view your desktop, but you still need to follow the normal precautions when letting other people view your desktop. This makes it much less useful for some things like remote help , but much more useful for others like creating a public area for collaboration.

Like x11vnc, tightvnc is designed to be run from the command-line. To start it, type: tightvncserver -nolisten :1 This will tell tightvnc to listen for VNC connections on port from anywhere on the Internet. Without the -nolisten tcp option, tightvnc will also listen for a different type of connection X11 instead of VNC , which isn't usually very useful.

Tightvnc's unusual design means that it can't create a remote desktop on the standard VNC port if you have an ordinary desktop running on your computer. There's no way to set tightvncserver to request access each time. There's no way to set tightvncserver only to accept the next connection, although see below for a similar solution.

Tightvncserver always requires a password, and will ask you to specify one the first time it's run. To set tightvncserver to only allow local connections, include the -localhost option. Once mode Tightvncserver can't be set to accept the next connection then stop listening for connection attempts.

But it can be set to automatically disconnect each client when the next client connects, and can be stopped after your connection is disconnected. To only allow local connections and automatically disconnect clients, start tightvnc by typing: tightvncserver -nolisten tcp -localhost -nevershared :1 Then when your client is disconnected by the next client connecting, type: tightvncserver -kill :1 Customising your session By default, tightvncserver provides a session with a simple window manager and a terminal.

You should use the name and desktop number that VNC gives you. Click "OK", and it will ask you for a password You should now get a window on your PC that contains an X Windows desktop that is running on the remote machine. When you are done with your VNC session, you should log in to the unix machine where you started it, and kill it with the command:.

You should only have one VNC Server running. To check your VNC Server processes, use the command:. For example, I can check my VNC processes on yeager, by running the following command on yeager:. Search this site:. Link Layer 2. Internet Layer 3. Transport Layer 4. Physical Layer 2. Data Link Layer 3.

Network Layer 4. Transport Layer 5. Session Layer 6. Presentation Layer 7.

You will need a VNC server if you want other people to see your desktop.
